SPECIFICATION forming part of Letters Patent No. 385,786, dated July 10,1888.

Application filed December 28, 1887. Serial No. 259.259. (No model.)

To all whom it may concern:

Be it known that 1, Cinemas A. BARTLIFF, a citizen of Canada, residingat Memphis, in the county of Shelby and State of Tennessee, haveinvented a new and useful Improvementin ChailrPumps, of which thefollowing is a specification.

My invention relates to an improvement in chain-pumps; and it consistsin the peculiar construction and combination of devices, that will bemore fully set forth hereinafter, and particularly pointed out in theclaims.

The object of my invention is to provide an endlcsschaiu pump withlinks, which connect the buckets together and are adapted to prevent thechain from becoming kinked or entangled while in operation, and therebyenable me to dispense with the wheel or pulley, which is usuallyarranged near the bottom of the well or cistern, and around which thelower side of the endless chain passes.

In the accompanying drawings, Figure 1 is an elevation of a chain-pumpembodying my improvement, showing the same arranged in position foroperation. Fig. 2 is a detached perspective view of a portion of achain-pump embodying my improvements. Fig. 3 is a vertical sectionalview of a portion of the same. Fig. 4 is a transverse sectional viewtaken on the line as m of Fig. 3.

A represents a series of buckets, which are made of sheet metal, of theform here shown, and have one end open and the opposite end closed. Theinner side of each bucket is open and the side walls of the same areprovided with flanges B, which are bent inwardly over the open side ofthe bucket, as shown.

0 represents a series of straps, each of which is made from a singlepiece of sheet metal, having its ends doubled over the central or mainportion of the strap until their edges meet, thereby forming loops D atopposite ends of each strap.

E represents a series of rectangular links which are employed to connectthe buckets together. The said links are provided at a suitable distancefrom their ends with crossbars F,which are engaged by the loop D, andbeyond the said crossbars extensions or arms G are formed at the ends ofthe links, which extensions or arms are bent at asuitable angle withrelation to the main body of the links.

The operation of putting the parts of the chain together is as follows:The loops D or straps O are first caused to engage the cross bars F onthe opposing ends of the links, so as to connect the latter together ina series. The flanges B of the buckets A are then bent outward flushwith the sides of the buckets, and are then caused to pass over theopposite edges of the straps, so as to cause the latter to cover theopen sides of the bucket, and the said flanges B are then bent inward onthe outer side of the said straps, so as to secure the same firmly tothe buckets and prevent the ends of the straps from being straightenedout and releasing the cross-bars of the links.

In Fig. 1 I illustrate the usual wheel or windlass, H, over which theupper portion of the endless bucket-chain passes, and from the same thesaid endless bucket-chain depends and extends into the well or cisternfora suitable distance. The arms or extensions G on the ends of thelinks bear against the inner sides of the buckets and cause the same tobe arranged in form of a semicircle at the bottom of the well or cisternand prevent them from coming close ,together, and thereby entangling orkinking the endless chain. By this means I am enabled to dispense withthe wheel or pulley which is usually employed near the bottom of thewell or cistern to guide thelower portion of the endless bucket-chain,and thereby effect an economy in the construction of the chainpump andenable the same to be operated as rapidly as may be desired without thedanger of its becoming kinked or entangled.

Having thus described my invention, I claim- 1. The combination of thebuckets, having the projecting loops D at their ends and the bent-overside flanges, and the links pivoted to said loops connecting the bucketstogether, and having the extensions G at their sides adapted to bearagainst the inner sides of the buckets, for the purpose set forth,substantially.

the extensions or arms G, adapted to bear against the inner sides of thebuckets, for the purpose set forth, substantially as described.

3. In an endless-chain pump, the combination of the buckets having theflanges B on their inner sides, the straps 0, having the loops D attheir ends and engaged by the flanges B, so as to secure said straps tothe inner sides of the buckets, and the links having the crossbars Fnear their ends, and the projecting arms or extensions G, the saidcross-bars F being engaged by the loops D, and the said arms orextensions being adapted to bear against the inner sides of the buckets,for the purpose set forth, substantially as described.

4. The combination, in an endless-chain pump, of the buckets having theloops at opposite ends on their inner sides and the connecting-linkspivoted to the said loops, and having the extensions or arms Gprojecting beyond their pivotal points and adapted to come in contactwith the inner sides of the buckets, for the purpose set forth,substantially as described.

5. The buckets having the flanges B on their inner sides, the straps C,forming the inner sides of the buckets, and having their ends doubledand bent to form loops D, the flanges B being bent over the edges of thestraps, for

the purpose set forth, and the links connectt ing the buckets andengaging the loops, substantially as described.

111 testimony that I claim the foregoing as my own I have hereto aflixedmy signature in pres ence of two witnesses.
